Type 2: This instrument shall have the capability for compensated static immittance and tympanometry under manual or automatic control of air pressure, and for the measurement of ipsilateral or contralateral acoustic reflexes. A Type 2 instrument shall be capable of generating pure-tone acoustic reflex-activating signals.

Type B tympanogram with a high ear canal volume (ECV = 3.2), consistent with a tympanic membrane perforation, a patent grommet or T tube. Type B tympanogram with a low ear canal volume (ECV = 0.1) indicating that the probe is blocked, either by wax in the ear canal, or the probe tip is against the side of the ear canal Normal Tympanogram.
